One form of this phenomenon involving a spinning rod inducing the inward motion of polymer solutions is called the Weissenberg effect. In thin layers, this phenomenon results in structures called Bénard cells. If the (*) Grashof number is much greater than the square of the Reynolds number, only the "forced" type of this process happens to any appreciable extent. It contrasts with processes relying on photons and on atom-to-atom energy transfers. For 10 points name this process of heat and mass transfer unique to fluids
